An
echo mic when properly adjusted can make a significant
improvement in the clarity of the radios modulation.
The goal is not alot of echo. The goal is the compression
effect gained from proper adjustment of the echo level.
The mic has a modulation adjustment inside the case
and an echo level slider bar at the top front of the
mic. The echo level should be adjusted for a minimal
amount of echo level. At that point the sound of the
radios modulation will be improved drasticaly.
